Benefits of Copper

Copper is an antioxidant found in enzymes that deactivate free radicals (pieces of molecules that can link up to form compounds that damage body tissues) and make it possible for your body to use iron. Copper also may play a role in slowing the aging process by decreasing the incidence of protein glycation, a reaction in which sugar molecules (gly = sugar) hook up with protein molecules in your bloodstream, twist the protein molecules out of shape, and make them unusable. Protein glycation may result in bone loss, high cholesterol, cardiac abnormalities, and a slew of other unpleasantries. In people with diabetes, excess protein glycation may also be one factor involved in complications such as loss of vision.
In addition, copper

• Promotes the growth of strong bones
• Protects the health of nerve tissue
• Prevents your hair from turning gray prematurely

But, no no, a thousand times, no: Large amounts of copper absolutely, and I repeat, absolutely will not turn gray hair back to its original color. Besides, megadoses of copper are potentially toxic. You can get the copper you need from organ meats (such as liver and heart), seafood, nuts, and dried beans, including cacao beans (the beans used to make chocolate).
